Noise Sensor (Microphone), POM-2735P-R


Noise Sensor

This is the POM-2735P-R microphone which can be used to monitor environmental noise. It is an omnidirectional microphone with an almost flat response in the entire frequency range of human hearing between 20Hz and 20kHz.

Microphone Features

  • Sensitivity: -35dB 4dB
  • Impedance: Less than 2.2kΩ
  • Omnidirectional
  • Frequency: 20Hz to 20kHz
  • Supply voltage: +3V standard; +10V maximum
  • Current Consumption: 0.5mA maximum
  • Sensitivity Reduction: -3dB @ 1.5V
  • Maximum Sound Pressure: 114.5 10 dBSPL, approximately
  • Signal-to-Noise Ratio: 60 dB

POM-2735P-R Documentation

Compatible with Waspmote

This sensor can be used in a Waspmote wireless sensor platform by plugging it into the Waspmote Smart Cities Sensor Board. It is highly recommended to purchase this microphone at the same time as a Waspmote and a Smart Cities board! The sensor requires calibration on the system with which it is to be used.

When you purchase this microphone with a Waspmote and a Smart Cities board, it will arrive pre-calibrated to return an output in the range of 50dBA and 100dBA with an accuracy of 2.5dBA. The calibration data will be stored in the Waspmote microcontroller's EEPROM between addesses 164 and 185, so make sure you do not overwrite those memory positions!
